Abstract

Measurements were carried out at Cairo and Aswan in Egypt for three years (1990–1992) using Eppley Ultraviolet Radiometers by the Egyptian Meteorological Authority. Also, the global solar radiation was recorded for the same three years at Cairo and Aswan using Eppley pyranometers. All the meteorological conditions of the two cities are collected, and the stratospheric ozone is measured by Dobson spectrophotometers. The ratio of the ultraviolet to the global radiation (UV/G) range between 2.7% (in winter) to 3.4% (in summer) for Cairo (lat. 30°). Aswan in the south of Egypt (lat. 23.5°) shows the inverse, where the ratio of ultraviolet to global solar radiation (UV/G) range between 3.9% (in winter) to 3.5% (in summer).
